Following statements are regarding to determination of filament formation by actin concentration.

A. The critical concentration (Cc) is the concentration at which G-actin monomers are in equilibrium with actin filaments.

B. At monomer concentrations below the Cc, no polymerization takes place. 

C. When polymerization is induced at monomer concentrations above the Cc, filaments assemble until steady state is reached and the monomer concentration falls to Cc.

D. At steady state, the concentration of monomeric actin below the critical concentration.

In garden peas, the allele for tall plants (D) is completely dominant to the allele for dwarf plants (d) and the allele for violet flower color (W) is completely dominant to the allele for white flower color (w). In a cross between a tall violet plant, with the genotype DDWw, and a dwarf white plant, what phenotypic ratio of the progeny would be expected from this cross?
